Profiles
Tapping on the
GPS Profile Selection
drop-down menu allows you to choose an appropriate profile:
Default
,
Automotive
or
Pedestrian
.
•
Default
profile is a good general profile suitable for most uses.
•
Automotive
profile is designed for in-vehicle use, providing quick location updates as the vehicle moves.
When the GPS module is set to this profile and the vehicle enters an area such as a tunnel where satellite
coverage is interrupted, it
will
attempt to predict the vehicle position.
•
Pedestrian
profile is designed for those using the GPS module while walking. It takes into account the
slower pace of the pedestrian when mapping the location of the user. When the GPS module is set to this
profile and the operator moves into an area where satellite coverage is interrupted, the GPS module
will
not
attempt to predict the operator’s movement.
AGPS (Assisted Global Positioning System) Tab
To determine your location, a GPS module receives data from three or more GPS satellites in fixed orbit
around the Earth. The GPS module triangulates your location based on the time it takes for signals to get to
and from the satellites. This works well in fairly clear areas – outdoors, for example. However, if you’re
attempting to triangulate your location in city centres where signals bounce off tall concrete buildings or from
within a building, the GPS module will have greater difficulty calculating a fix.
AGPS
reduces
Time To First Fix
(TTFF) and increases the likelihood of finding and keeping a fix in poor
coverage areas such as indoor sites. AGPS downloads satellite ephemeris (orbital) data to the Omnii periodi-
cally through Wi-Fi or WWAN. The downloaded data is used by the GPS module to speed the process of
getting a fix.
